Hanz, W1JSB and I hiked near Profile Falls in Bristol today. We worked Germany, Canary Islands, the Netherlands, Ontario and North Carolina.

Here’s a photo of Hanz setting up his gear on the bridge abutment.

We set up our gear on the old rail right of way on the edge of Profile Brook. The rails are gone and the bridge is unused, but the stone abutment remains. It’s a pretty spot. We operated here in the early spring.

I heaved a line into a tall maple tree near the old bridge site. We pulled up a 33 foot wire and I connected a 9:1 unun and started operating the KX3 on 15 meters. The Worked All Germany contest was in full swing, so we worked quite a few German stations. Here’s my log:

19 Oct-13 1900 21.008 CK3AT CW 599 599 Ontario
19 Oct-13 1901 21.009 DK9OY CW 599 599 Germany
19 Oct-13 1903 21.016 DL0LK CW 599 599 Germany
19 Oct-13 1920 21.020 DK0SU CW 599 599 Germany
19 Oct-13 1924 18.085 KS4S CW 599 599 NC
19 Oct-13 1928 18.092 EA8BBJ CW 559 599 Canary Isl

After operating on 15 meters for a while, Hanz took over. He operated his souped up 20 meter SWL rig in the yellow Pelican box. He worked several Germans.

After a while we switched to 17 meters with my KX3. Hanz worked KS4S in North Carolina and PA3DZM in the Netherlands, and I worked EA8BBJ in the Canary Islands.

The afternoon sky had clouded over and most of the leaves were off the trees. But the air still had a rich fragrance of fall and the lingering warmth of Indian summer. We hadn’t operated together for nearly a month, and it was
great to get out with our QRP gear again.

Today was Indian Summer. Judy and I walked over Shute Hill to Swain’s Farm. I worked Belgium, Netherlands, Morocco and England.

Indian Summer is what we call the last few days of extra-warm weather before the cold settles in for the winter. It was a gorgeous day. It may be the last good day with beautiful fall colors. It was 72F with a crystal blue sky.

The pathway over the hill is about 2 miles. We walked on a crunching carpet of rich colored leaves. Judy got a quick snapshot of me as we neared one of Swain’s fields.

The view from the hay field is fantastic. We gazed out on the Belknap Mountains. In the foreground the rich grass shimmered in the sunlight.

I heaved a line over a maple branch nearly 50 feet above the edge of the field, and I pulled up a 33 foot wire. I hooked up the KX3 and tuned around 10 meters. It was active, and I quickly landed a QSO with ON7DU. Johan was a 599 and gave me a 579 from Belgium. Then I worked the Netherlands. PA5WT was calling CQ and I answered. Kees gave me a 449. He was a strong 599.

Then I switched to 17 meters. Med was calling CQ from Morocco. CN8YR gave me a 339 and he was a 579. I went back to 10 meters for a final QSO with M0UNN in England. I exchanged a quick 599 with Jay and packed up the gear.

The view from the operating position was the greatest! In the past I’ve worked the QRPARCI Fall contest from here, but I couldn’t make it this year. Rain is forecast for tomorrow. I sure am glad I was able to get out today.

We’re getting ready to hit the road for vacation.  It’s been a whole year since KD2CHE and I tied the knot on a cliff overlooking Lake Tahoe.

Xiegu X1M

We’re not going to be heading back there yet, but wandering through New York’s North Country a bit.  I’m expecting to get a little portable QRP operation in as we poke around up there.  In anticipation of the trip, I picked up a spare power supply from my brother a few weeks ago to use with the Xiegu X1M, and any other 12V items I have or may acquire when I’m not near my main setup.  I decided to assemble the “motel room” version of my QRP setup here to see how it works.  I have the Xiegu, my Emtech ZM2 tuner, mic, the spare PS, and a small amplified speaker sitting here on the couch.  A string of 2 alligator leads is running from the ZM2 to the feed-thru from my random wire up near the window.  Everything powered up, and tuned up, so I decided to answer a couple of calls on 15M.

I made USB contacts with UT7UJ in Kiev, and S51ZZ in Slovenia from my test station on the couch here in Long Island.  Not bad for 5 Watts.  This little rig is full of surprises.  I also just found out from Ed at Import Communications through a post to the Xiegu X1M Yahoo group that he is going to be offering upgrade kits for the earlier X1M to upgrade the front panel and display to the newer version, as well as a strong possibility of a firmware upgrade that will cure many of this rig’s little issues.  The firmware upgrade has already been released for the newer model.

Now, time to pack it back up, and hit the road.  73s de Neil, W2NDG

Hi all,

The Lydford from Walford

I am in the process of updating radiokitguide.com.  If you can think of any new kit sources that I haven’t covered yet, please leave a comment here.  I am looking for RECEIVER, TRANSMITTER, and TRANSCEIVER  kits.  I will cover accessories at a later date.  If you know of a spectacular source of accessory kits though, send it along anyway.  I am adding a couple of new sources, and making changes to YouKits, Small Wonder Labs (goodbye), TenTec, and several others.  Thanks in advance for your help!

It’s always nice to find that other people’s findings match your own. PA0RDT is famous for his design of the mini-whip, a very small but effective long- and medium wave antenna. Roelof found that the magnetic component of a radio wave could more easily go through obstacles, while the electrical component was more contained within a closed space, like a house. This means that the electrical component of noise generated by appliances in the house stays inside – mostly – while the magnetic part travels outside the walls. Thus his mini-whip design picks up the electrical component only and amplifies that. If the antenna is placed some distance from interfering obstacles it will result in a strong, but relatively noiseless signal. I build one and can say it really works.

But amplification comes at a price: IM and overload. Passive loop antennas have non of the afore mentioned problems. Since the beginning of my radio days I have always had a one metre square loop antenna for MW and LW and deep in my heart I longed for one. So I build one again, but this time bigger: 180 cm square with the corners clipped. Tuning is done remote with a BB112 varicap. The circuit was once published by the Benelux DX Club and I’ve had it for over 25 years, but never build it to this day.

Because of bad weather I could only put it up last weekend and boy, what was I disappointed. It seems it picks up all the television noise from the whole neighbourhood, with added noise from within my own house. The mini-whip is clearly better than the loop, so PA0RDT is right. But using another laptop power brick helped a bit and after firing up Argo it seemed that despite the noise the loop was still proving itself useful.

The loop tunes from 136 kHz to just above 400 kHz, which covers most of the NDB frequencies. Even though long wave beacons are on the decline there are still a lot of them. I heard some 30 new ones over the weekend, both in the daytime and at night. Argo is a great tool, sometimes beating my ears in picking up signals. Here some screen shots.

Locator “O” on 201 kHz and PQ on 202 kHz, both unidentified.

An odd one heard on 220 kHz: BRBA5. Notice that the dash in the letter “R” is longer than the other dashes. Ears won’t notice this, but with Argo you can see it.

Three beacons on the same frequency of 380 kHz: LM, OB and sandwiched in between YU from Hualien (Taiwan’s east coast).

NDBs are fun to DX, but my goal is to do some 2200m DX. Without any voltage applied to the varicap the loop is tuned to 136 kHz, which means I can leave it on all night and hope that I can detect some signals from Japanese hams, or maybe the Philippines. Unfortunately Chinese hams are not allowed to use 2200 meters and I don’t know of any Taiwanese hams operating this low. Help! I think I am becoming “low-nely.

Shortwave radio history – communications in and out of New Zealand in 1939. This history is rich with adventure and successes that are profound. Our modern communications all stems from this historic work…

This is a short film about the romance of the radiotelegraph service that utilized the high frequency spectrum known as “shortwave” (from 3 MHz up to 30 MHz) as well as the longwave and medium frequency spectrum (below 3 MHz).  This is a short film about communication to and from New Zealand on these shortwaves, using Morse code (eventually, using CW modulation). This film is a 1939 Government film scanned to 2K from a 16mm combined B/W reduction print.
